Hi guys, wodering if the sunblind motors for the front sunblind left rear motor C2D24885 and the right side for rear sunblind motor C2D16891 are actually the same units??
As in are they actually interchangeable?

i have examined pictures of both and cannot tell the difference between the two with exception to the part numbers, i need to replace the front blind motor........ i think in my XJ before i sell her, same old problem as everyone, motor runs but the blind does not move, have ordered the feet from SNG Barrett but now searching for a left side front blind motor and i cannot tell any difference between the two part numbers, they both seem to have the same orientation upside down with the mount brackets in the same place and drive gears then the other way up seem to be exactly the same too.Even the flexible drive shafts seem to be the same length.

I also ordered the centre retaining clips C2D25833, as my centre one seems to be bent over so the headlining between the two sunblinds front and rear does mount firm to the roof.

While i am here i have to ask if there is anything else i need to purchse to get the job done?

 

Me too, here in NZ same problem. Is it always the front that stops working?
I was hoping that the gear wheel(s) would be separately replaceable. Haven't had a chance to pull the headlining yet - owned the car 4 weeks :-)

 

Unfortunately mate it does seem that way, when you research the topic its all over forums and internet. I bought mine and the first day i drove it i hit the blind button and it did not work from day one for me and i was only the second owner at 60,000 km.
Its a known issue but unless it happens under warranty then we find ourselves where we are now.
Looking at the gear wheels you could probaly replace them as they seem like a pressue fit with a kind of rounded off drive stem to hold the gear in place in a simmilar fashion to a solid rivet. So i9n theroy you coludl zap it with a tig dot to hold it in place.
i guess tou could even drill and tap the shaft and fit it with a larget headed machine thread screw to hold it down as well. The only thing being having someone to re machine a new gear for you, if indeed that is the actual issue of the loss of drive function.
Which in my research does seem to vary from anything to the guide feet, motor out of alignment and worn gears.
I am no expert though as untill the hoodlining is down it seems like something hard to analyse correctly, in theory the guys here have stated it is a poosible job to DIY, but i am very apprehensive of getting into it, its territory i have never been into with the possibility of causing more damage if not removing the hoodlining correctly.

Best of luck with yours mate, mine has only done 11000 km in the last 3 yrs so my odo is 71000kms, not because there is anything wrong with it, the horror stories with the V8 abound but i have experienced no issues, even after installing the stage 2 tune from Velocity AP, maybe i was lucky, but most the issues were covered off by the first owner, eg plastic water pipes, water pump and timing gear, all i did was fully service the ZF box at 60000kms, flush, new seals all through and correctly fill with original ZF fluid. Lol i looked at my last service odo last year at 69000kms so in the last year have only covered 2000kms. She is my baby, gets a regular run to keep the important juices flowing..

Hopefully @clubairth1 or @XJsss or someone with a simmilar depth of knowledge will swill by and let us know.

Kind Regards

Sorry I have not had to work on those yet?
But I am a bit confused as you mention right and left?
Is this the sun roof blinds or the rear side window sun blinds?
I think you are talking about the rear side window blinds?

Before ordering anything I would take it apart and look. Maybe something that can be fixed without replacing anything?
My guess would be they are just mirror images of each other and can't be interchanged. Otherwise I don't think Jaguar would list two part numbers.

Sorry @clubairth1 , refering to the sun roof blinds, front blind motor on the LHS toward the rear of the vehicle and rear sun roof blind motor on the RHS.

i found the mistake, the part numbers current for right side is C2D24885
left side is C2D24886

the pics i was looking at are simply the same part C2D16891 which has been superseded by C2D24885, my mistake Clubairth1.

 

OK glad you found that as I thought they were the same part too.
But your parts links both show the same part number 25 in the diagram? Yet they call them right and left?
Their pictures indicate they are used in exactly the same spot too? Not sure those listings don't have an error in them somewhere?

To further complicate things I found this part number too? C2D23452 but it's listed for 2016-2019 XJ's?
So it looks like Jaguar updated this part for the 2016 model year and the numbers you posted work on XJ's from 2010-2015?
Sunroof Drive Unit

Here is an auction with some pictures and it does look somewhat different.

@clubairth1 yes!!! you are spot on, the parts diagram shows as part X, but then the diagram does not show both units, then when scrolling to find the part number it gives you two stating one as left and one as right.
So you would be correct as one being a mirror.

You are spot on right again with the recent part number codes too from 2016 and up, so yes am looking for the older part number for the left passenger side, dont forget i am in Australia so its opposite to the USA lol so makes auction listings description a careful process,,,,,,,, all this is enough to give someone Dyslexia.

Thanks for those links too, i am so glad i did not drop the money on any motor unit yet, it has been a tad confusing to wrap my head around it all so far.

I will take down the roof lining and inspect when my parts from SNG arrive and go from there, see if i can get away with fix without having to replace the whole assembly,

Thanks for your help, i really appreciate it,

Kind Regards

Ok great!
Did you order both part numbers? Right and left units?
I had an additional thought? Since Jaguar changed the part number for 2016 and up do you think that part would fit and maybe it would be an improved version? It does look different but not much in the pictures.

Just a big guess here as we really have had very little postings about sunroof motor problems? So not sure why Jaguar would spend the money to change them?
Note I find C2D23452 as the left one and C2D23451 as the right one if anyone is looking for the 2016 and up parts. What's interesting is these look to be mirror images of each other but a big difference in price as the right one is $250 but the left one is almost $400?

Post back if you can on how the repair goes because as I said this is not a known problem area on the X351 XJ.

If you're gonna drop the headlining to do this job, do it once and do it right...replace the entire drive units. You don't want to replace the drive spindle, to only have the motor or drive cog then fail 5 minutes later. Whilst there, replace all the blind guide shoes front and rear for the same reason. Remember to retension the blinds correctly. Rather than try to locate the tiny hole to lock the shaft into place, I just let mine unravel, removed and rewound as per the service documents I found online, located the locking hole and held the tension on the blind by using a 1mm drill bit. Maybe grab some plastic headlining trim anchors as these can easily break and the rattling will drive you nuts lol. To refit the blinds on the guide shoes, have a look at my posts and the video.

 

Thank you fossberry! I knew someone had experience with this and it was not me!
Any chance you could post some part numbers?

Since we have moved on to the blind and it's problems I do have a nice document with pictures that will help with the pin and blind?

Post back with your results if you can?

i will need to add a few more more extra hood lining pins/clips, SNG Barratt U.K. are out of the other types i need or are not manufactured anymore, i only purchased the ones across the divide that bridges the front and rear sunroof sections,

i am having trouble again with partnumbers due to superseded parts and again with 2011 X351 seem to be specific up to 2013 MY i think.
i will check out other U.K. Jag specialists, everyone in the USA like jaguarparts.com will not ship international orders so i go there for part numbers but have to try and find someone elsewhere to order internationally with econonmical postage options, i do not know what happened in the U.S. but international postage now is a killer to Australia, i live in a regional city, cities here are not like cities in USA, you cannot just run into town and get the things you need, the usual response is "we can order it for you" i live in W.A. we joke about it and call it Wait AWhile

It will take a while to trace down the motor casting kit, the blind feet are an easy find and found them on SNG and are on the way.
I have all the PDF's for the hoodlining and sunblind, rollers etc so am good there, i tried finding video of the hoodlining removal as several have done it but i have not been able to find anything, watched @fossberry vid he made which is handy, i dont think i would have figured that out unless someone showed me.
.
Will be going slowly as i have never done this before but will wait till i have all the parts on hand. I will try to do some vid and upload here so that others can see whats involved and become a visual tutorial sort of for those uninitiated like myself. The manuals leave alot to the imagination, hell i cannot even see my blind feet (no pun intended) so will drop the lining so i can see what is going on.
i think i have read through most of the threads here and seen all the tube vids associated.

A huge help for me was removing the sunroof glass. Another way would be a inspection mirror to locate the clip that the guide shoes locate on to. These are side-specific. If you run the new guide shoes along the runner at a oblique angle, you'll feel it click onto the drive spindle. As you say, the service guides are a help but not the be all and end all. Just take your time. You might have a gap between the blind and headlining once replaced. I recalibrated it with my diagnostic tool to sort this.

 

The headlining trim clips I used are C2D3465010. Half a dozen of these is a good number.

Left side sunroof sliding blocks: C2D30280
Right side sunroof sliding blocks: C2D30281

Front left panoramic roof blind motor and mechanical assembly: C2D16892

Rear right panoramic roof blind motor and mechanical assembly: C2D16891

The above was for my 2011 portfolio

 

@fossberry thanks for your parts list, really appreciate it, ordered from David Manners in the UK, pack of 10 trim clips C2D3465010 and a new sunroof blind casting kit C2D24886.
Postage from the UK hurt, but cannot wait around forever waiting in the hope a part comes up on the bay.

So had a play the other day and raised the sunroof as per the manual, after seeing your vid located the clips that locate after rotating the front sun blind bar into place at either end of the sun blind front bar left and right and now i understand where the Blind feet are and how they locate into the small black plastic tabs inside the blind track runner, omg so simple once you have done it.
To be honest i thought the blind feet somehow ran inside the track as the manual depicts the rotating into place leaving them basically invisible, now i realise they are holding the metal front blind bar behind the sun blind material, lol it all makes sense now.
My blind feet do not bind at any point in the track but will replace them anyway as the parts are ordered, i did run the blind motor and its no longer making a grinding sound which tells me the motor drive gear is not even in contact with the flexible drive shafts so that part is just worn out i guess.

I did find in my research that Mercedes parts for the flexible drive shafts are available, and work in the same way as our jags, but have no idea as to part compatibility or tolerances or drive gear size and toothing, but it may be possible to replace the flex shafts and the motor drive gear with the Merc parts and save a ton of coin without having to replace the entire casting kit rendering the part a serviceable item and not a full replacement.

Why Jag has decided to make the part non serviceable is disappointing when Merc and many other brands who use the same setup make them as a fully serviceable unit.

Yeah was damned difficult trying to decipher the manual and make sense of it. Once I could see the guides from above it all made sense, and decided a small video of how it clicks in would be of benefit to others. Yeah it grinds my gears (pun intended) that you can't simply just replace what's needed and leave what's not, but I guess everything is new and don't have to worry about something failing (hopefully) again.
